ScreenerInterpolatedIvHorizon

Expected move and implied volatility for one fixed calendar-day horizon. An exact expiry requires at-the-money call and put observations less than 120 seconds apart. Volatility is their mean implied volatility. Implied move is 0.85 times their summed theoretical prices. Exact-expiry metrics are encoded as floor(value * 1000). Values between expiries use total-variance interpolation for volatility and squared-value interpolation for expected move, then round the source integer up. When only one surrounding expiry is available, each source integer is adjusted by one unit per calendar day from the known expiry to the requested horizon.
